James Van Der Beek is now a proud papa, two times over!

The Dawson's Creek actor announced via Twitter Tuesday that he and his wife of 18 months Kimberly Van Der Beek (formerly Brook) welcomed a son into the world.

"Had my first son this morning…Well, actually, my wife had him. I just caught him. Wow. Heart expanding way faster than my brain..," the 35-year-old tweeted.

"If you could bottle up and distribute this feeling, I swear there'd be no more war. #fatherhood," he added.

No word what the little one's name is, but this is the second child for the Van Der Beeks: their daughter, Olivia, is 17 months.

James was previously married to actress Heather McComb from 2003 through March 2010, but they didn't have any kids.
